About the position

Increasingly, operational and maintenance decisions are made based on digital twins (models) of a process system. Examples include production optimization based on production system models, soft sensors for flow metering, or disposed water quality management, maintenance schedules.

The main objective of this project is to study and develop strategies for automatic calibration and maintenance of the process model when the process and the measurement sensor properties change. A second aspect of the research will be to study how this affects the decisions that are made based on the model.

This PhD position is part of the Centre for research-based innovation named subsea production and processing (SUBPRO). The Norwegian oil and gas industry is in the forefront with respect to subsea field developments, but new and innovative solutions are still required to meet current and future challenges. To accelerate the level of innovations within subsea production and processing, SUBPRO was established at NTNU in 2015. The Centre is supported by the Research Council of Norway and several international industry partners. For more information about SUBPRO, please visit our website: www.ntnu.edu/subpro

Main duties and responsibilities

  • This PhD project will explore the use of tools from system identification, first principles and data-driven modelling, and numerical optimization to         
    • Quantify the accuracy of the model
    • Determine when and how to update the model structure and its parameters
  • A special focus will be on combining system identification approaches and first-principles modelling, in order to ensure that the model evolves together with the process
  • Study the interplay between the model update and achieving optimal operation
  • The developed methods may be tested in the SUBPRO Erosion lab and industrial case studies from the industrial partners in SUBPRO
